1. On methods for estimating oceanic flow
Sammanfattning : The aim of this thesis was to estimate and possibly quantify ocean flow by utilizing conventional and novel observational methods as well as model results. Motionally induced voltages, from a cable-based observational system in the Baltic Sea, were analysed to determine their utility for ocean monitoring. LÄS MER
2. Development of Alumina Forming Alloys for High-Temperature Energy Applications
Sammanfattning : Liquid lead as heat transfer fluid presents attractive features for future power technologies, such as next-generation nuclear reactors, thermal solar power, and thermal storage. Liquid lead has excellent heat transfer properties well suited for operating at high temperatures. LÄS MER
3. Micro-structural based acoustic modelling of anisotropic open cell materials
Sammanfattning : A method for the calculation of the acoustic performance of open-cell foammaterials is discussed. From a known micro-structural geometry and theconstituent material, the relevant acoustic properties are computed using apreviously published analytical method for the calculation of the dynamicdrag impedance and a previously published method for the calculation of theelastic moduli.

4. Ridged sea ice modelling in climate applications
Sammanfattning : This work aims to increase our understanding of the nature of large scale features of sea ice from a dynamics point of view.Sea ice plays an important part in the exchange of heat and humidity between sea and air and thus is an important component of the climate system. LÄS MER
5. Non-Invasive Assessment of Liver Fibrosis with 31P-Magnetic Resonance Spectroscopy and Dynamic Contrast Enhanced Magnetic Resonance Imaging
Sammanfattning : The present study aims at demonstrating phosphorus metabolite concentration changes and alterations in uptake/excretion of a hepatocyte specific contrast agent in patients with diffuse - or suspected diffuse - liver disease by applying two non-invasive quantitative MR techniques and to compare the results with histo-pathological findings, with focus on liver fibrosis.In the first study phosphorus-31 MR spectroscopy using slice selection (DRESS) was implemented.
